Abstract:With the day-by-day improvement of infrastructure construction, more critical roads are being built in the central urban area, but will face the complex environment of old road reconstruction and adjacent subways, facing complex environments such as the demolition of old buildings and the adjacent subway, which puts forward the higher and more precise requirements and challenges for subgrade treatment. Taking the treatment of the subgrade in an old urban area with the subway line as an example, based on the concept of cost-effective and project characteristics, and combined with the comprehensive analysis of project needs, safety requirements and cost, a recommended scheme is achieved, which can provide some reference for similar projects.
